HOT-WATER H EATER.
SPECIFICATION forming part of Letters Patent No. 560,268, dated May 19, 1896.
Application filed. December 10, 1895. Serial No. 571,616. (No model.)
To cir/ZZ whom it may concern:
Be it known that I, ROBERT I-I. LAIRD, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Hot Water Heaters, of which the following, when taken in connection with the drawings accompanying and forming a part hereof, is a full and complete specilication, suftici ent to enable those skilled in the art to which it pertains to understand and make the same.
My invention relates to the class and kind of liet-water heaters whereby water is heated and used, primarily, for warming buildings, the heated water extending from the hotwater heater through a system of pipes and radiators back to the hot-water heater andin a cooled condition, having parted with its heat or the greater part thereof by radiation and for the purpose designatedthat is, for the warming of buildings; and it is the object of this invention to obtain a hot-water heater wherein perfect combustion of the fuel employed shall be obtained, and the whole or a very high percentage of the resulting heat shall be retained in and by the water passing through the device embodying the invention and so utilized. Y
A further object is to obtain a hot-water heater which will require but little care and attention when in use, and which shall be easy of manipulation and safe.
A further object of my invention is to obtain a hot-water heater simple in construction and not expensive, easilyput in operative condition by persons not specially skilled therein, and which shall be durable. It is to be understood that water heated by a hotwater heater embodying my invention is well adapted for all the uses to which any and all water of like temperature is adapted, and that the heat, if any, remaining in the products of the combustion of the fuel consumed therein, as such products pass from the heater, can be put to any suitable use desired.
In the drawings referred to as forming a part of this specification, Figure l is a vertical sectional view of a hot-water heater embodying my invention; Fig. 2, a top plan View thereof; Fig. 3, a horizontal sectional view on line 3 ofFig. 1, viewed in the dibodying my invention is built up of hollow metal rings A A and A2 A3 A4, preferably of cast-iron, such rings having the extensions a a, respectively. The extensions a a have therein the vertical partitions cd a', respectively, whereby when the hollow metal rings are placed one above the other, as illustrated in Fig. 1 of the drawings, water may extend from the inlet B in the extension a of the adjacent and lower hollow ring, from thence into the ring and around it, and from thence upward into the like extension a of the ad jacent and next higher ring. Such water go ing out of any given hollow ring may leave itpn the opposite side of the partition a in the extension a thereof from which it enters such ring.
In order that the products of combustion in the fire-pot or fire-chamber O may extend between walls backed by water, the hollow rings A A and A2 A3 A4, respectively, are placed as illustrated in Fig. l, a2 a2 being the waterways or water-receptacles of the hollow rings A A and D the passage-way therethrough for the products of combustion, and a4 a5 a@ the water-ways or Water-receptacles of the hollow rings A2 A3 A and D2 D3 D4 the passage-ways therethrough, respectively, for the products of combustion. The products of combustion in passing through such passage-ways D D2 D3 D4 and passage-way D', hereinafter described as connecting passage-way D with passage-way D2, part with their heat, or with a portion thereof, to the walls of the waterreceptacles adjacent thereto and forming the passage-ways, and by conduction raise the temperature of the water contained in such hollow rings.
The combustion-chamber O has an updraft through the grate-bars O from the ash-chamber, and also a downdraft from above the mass of burning fuel therein. To obtain the required supply of air for the downdraft, and
ICO
that such air may be heated, I in terpose between the hollow rings surrounding the repot or fire-chamber C and the hollow rings surrounding the respective passage-ways D2 D3 D4 the air-supply chamber E, such air-supply chamber being thereby located directly above the iire pot or chamber C. Through the side walls of the air-supply chamber E there are placed air-inlet passage-ways e c, and to connect the passage-way D, for the product of combustion, with the passage-way D2, I construct the vertical passage-ways D' D' D' D' in the side walls of the chamber E, between the inlet passage-ways e e. The eX- act number and comparative size of the airinlet passage-ways e e and the passageways D' D' D' for the products of combustion are not necessarily as illustrated in the drawings.
e' e e' are perforations in the bottom of the hot-air chamber E, through which air supplied to the fire-pot or fire-cha1nber C passes from hot-air chamber E.
F F are grooves formed on the inner face of the hollow ring forming the lire-pot or firechamber C, such grooves forming ducts or conduits whereby air is supplied to the body of the burning mass in the fire-pot when the fuel therein extends above the lower edge of the hollow ring A2. In constructing these grooves the back ff thereof, respectively, is made wider than the front opening j" f thereof, to prevent such groove becoming clogged by pieces or lumps of coal. It will be observed that hollow circular ring A' does not extend to grate-bars C' and that the products of combustion extending downward into and through the mass of burning fuel in fire-pot C can escape therefrom underneath the hollow ring A and from thence pass upward in passage-way D.
H I-I are projections or fingers on the lower edge of the hollow ring A', between which the products of combustion pass in leaving the fire-pot C. The products of combustion from fire-pot C, passing up the passage-way D, part with a portion of their heat to the Walls of the hollow rings A A', and to increase the surface with which such products of coinbnstion will come in contact the projections I I are placed on the walls of such hollow rings in the passage-way D, and like projections extend from the hollow rings A2 A3 into passage-ways D2 D2, respectively. I find in practice that even with these projections I I such products of combustion are in a highlyheated condition when passing through the passage-ways D D and that by the addition or supplying thereto at such point of heated air from the hot-air chamber E additional combustion is obtained, and I therefore construct the passage-ways .I J from the hot-air chamber E to the passage-ways D' D', respectively. tending through passageways D' D', together with the air admitted thereto through passageways J J, respectively, extend through The products of combustion exv passage-way D2 to the space K underneath the dome A5, and from thence pass downward in passageway D3, between hollow rings A2 A", to space K' above the hot-air chamber E and from thence upward in passage-way D", and are discharged from the liet-water heater through opening A,
To enable one to readily clean the firechamber or fire-pot C, opening Il, closed by door Z, is placed therein, extending through the hollow rings A and under A'.
L' is an opening closed by door l', extend ing into the space K' to enable such space or chamber to be cleaned. Fuel is fed to the fire-chamber or lire-pot C through opening M, such opening being closed by door m. (Sec Fig. 3.) To obtain access to ash-pit N, opening N' is made in the wall thereof, and to obtain access to passage-ways D2 D3, respectively, the openings O O are made through the dome A5, such openings being closed, respectively', by doors O O'. The several hollow rings are secured together by bolts I P, inserted in slots P' P', respectively.
Q Q is packing interposed between the extensions a a, respectively, of the hollow rings to render the same watertight.
The operation of the hot-water heater cmbodying my invention is extremely simple, and may be briefly stated to be as follows: Fuel being introduced into fire-chamber or fire-pot C (through opening M) and ignited, the products of combustion obtained thereby will pass through passage-ways D, D', D2, D, and D4, respectively, and to a suitable chimney. In such course of such products the water contained in the several water-recel t-acles described will be raised in temperature thereby, such products of combustion being correspondingly cooled. As the products of combustion extend through the passage-ways D' D' and additional air is supplied thereto, additional combustion will occur in such passage-ways D' D and in passageways D2 D4. The grooves F F allow air entering the iirechamber C from the hotair chamber E to ex.- tend well into the mass of burning fuel in the firechamber along the edges of such burning fuel, and the projections in the passage-ways D2D3present great surface to the heated products of combustion, as well as a considerable mass of material to be heated thereby. I prefer to construct the walls of the hot-air chamber E, as well as the top and bottom wal ls and the side walls, of fire-brick or fire-clay, such material being well adapted to withstand the heat of the iirechamber, as well as to become itself highly heated and thereby adapted to impart a high degree of heat to the air contained in such hot-air chamber.
